Samsung Unveils 840 EVO mSATA SSD

In conjunction with updates to their (surprisingly, actually fairly competent) OEM SSD software, Samsung is trotting out a new, high-density SSD in the form of an mSATA-equipped 840 EVO. mSATA drives allow both manufacturers and end users to pack in some speedy flash storage into even the thinnest laptops being sold today.

The drive uses Samsung’s latest 10nm class process – the company started producing storage chips for sale on this node earlier in the year.

It’s thanks to this process that you can score one of these mSATA 840 EVOs with a whopping 1TB of storage – all in a package just 3.85mm thick and weighing 8.5 grams (that’s roughly 0.15 inches and a third of an ounce, respectively). Samsung is promising that the highest-end SKU will accomplish maximum sequential read/write speeds of 540MB/520MB per second, with IOPS hitting 98,000 for random reads and 90,000 for random writes.

The new software includes enabling RAPID on its flagship Samsung 840 PRO SSDs, which should result in some noticeable performance improvements by leveraging unused RAM and CPU cycles to cache commonly used data.

Samsung projects the mSATA 840 EVO to be available globally later this month, with various introduction dates based on region; cost will vary between SKUs, depending on storage capacity of the drives.
